It is essential to connect the toilet tank and bowl tightly using the toilet tank bolts. Connecting the bowl and tank will help to prevent leaks when flushing. Another name given to toilet tank bolts is tank-to-bowl bolts. You need to know that these bolts are not strain-bearing, so they don’t need to be extremely tight. The function of the bolt is to ensure that the toilet bowl is securely connected to the bowl without leaking. In some cases, you may only need to tighten the toilet tank bolts using your fingers. If you need a wrench to tighten the bolts, ensure that you do that carefully.
